HSS - What is the difference?
High Speed Steel
Properties: General term for steel with high wear resistance and heat resistance, used in all variants (R, G, E).
Applications: Standard tools for drilling in metal, plastic, and wood.
High Speed Steel - Rolled
Manufacturing method: Rolled manufacturing process (simply formed)
Properties: Cheaper to manufacture, lower precision, rounded cutting edges, slightly softer than ground drill bits
Applications: Lighter work in soft metals (aluminum, copper), wood and plastic
High Speed Steel - Ground (ground drill bit)
Manufacturing method: Ground manufacturing process
Properties: Higher precision and sharpness, sharper cutting edges, better performance than HSS-R, suitable for drilling in harder materials
Application area: Steel, harder metals and alloys
High Speed Steel - Enhanced (cobalt-reinforced)
Manufacturing method: Ground and cobalt-reinforced.
Properties: Typically contains 5–8% cobalt, providing better heat resistance, wear resistance, and durability. Ideal for high-performance drilling in hard and tough metals
Applications: Stainless steel, acid-proof steel, titanium, and other high-alloy metals
